Question

Write a function rule that relates r and t.

Input r: -2, 0, 2, 4, 6
Output t: 0, -1, -2, -3, 1

Answer 1

Answer:
`t=-(1)/(2)r- 1`

Explanation:

For a lineal equation
`t=mr+n`

For r=0 and t=-1

`-1=m(0)+n\\n=-1`

For r=-2 and t=0

`0=m(-2)-1\\m(-2)=1\\m=-(1)/(2)`

Them
`t=-(1)/(2)r- 1`

???? The output for 6 is 1????
